Hi Ken: The M3 Semiconductor Analyzer does what you're asking for (PIC based), See http://www.prc68.com/I/MTE.shtml#Xistor Have Fun, Brooke Clarke http://www.prc68.com/P/Prod.html Products I make and sell http://www.prc68.com/Alpha.shtml All my web pages listed based on html name http://www.PRC68.com http://www.precisionclock.com http://www.prc68.com/I/WebCam2.shtml 24/7 Sky-Weather-Astronomy Web Cam >Has anyone ever put together a programme/circuit >using a PIC to identify transistors? Including figuring >out which leads are which, and whether the DUT is >NPN, PNP, SCR, NFET, PFET, or UJT?
